It's not a guarantee, but it should catch most such programs.
Well, I did, and found three instances of that combination of letters...all in my calibre file!
c:\program files\calibre\PyQt4.QtGui.pyd (dated 2/2/09)
c:\program files\calibre\QtGui4.dll (dated 2/2/09)
c:\program files\calibre\library.zip [PyQt4\QtGui.pyo] (dated 5/29/09)
(This is with the 0.5.14 installation put back after uninstalling the 0.6.x).
Are any of those files leftover from an old, old installation maybe, based on the date?
